Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.In addition, hereafter for convenience, institute
The "upper" of reference, "lower", "left", "right" are equal to that the directions such as the upper and lower, left and right of attached drawing itself are consistent, " first " hereinafter,
" second " etc. is to be distinguish in description, and there is no other particular meanings.
From the manufacturing device and manufacturing method of thick-wall bend disclosed in Chinese invention patent CN1212903U, background technique
In it is known that the reason of pipe fitting 5 is using heavy wall can be in terms of the following two for: first, in terms of processing technology, due to pipe
Part 5 not only needs the right angle for being bent approximately in two fluid channels, subsequent also to carry out screw thread process to pipe fitting 5, in order to ensure spiral shell
The machining allowance of line processing, so to select heavy wall pipe 5；Second, requirement of the fluid means to pressure-resistant performance in recent years is got over
Come higher, this wall thickness for allowing for pipe fitting 5 also comes thicker.
In addition thick-wall bend compacting tool set development is also described, specific as follows:
Therefore, heavy wall pipe 5 is difficult with minor radius bending manufacture at actually required elbow thick-wall bend 6,
The reason is that can green compact pipe and thinned tube wall.Then, the shape that one piece of metal thick plate curves it elbow bend is cut out, is used as curved
Capillus base, then drilling processing is carried out respectively from the blank two sides, the fluid channel of substantially straight friendship is formed, the spiral shell at both ends is then processed
Line.
But according to such manufacturing method, the cutting process of blank is 2 drilling processings and 2 screw thread process.Add
Work process is more, and the preparation section of blank is also more.Further, in drilling processing, in the crossover sites of substantially orthogonal fluid channel
Burr is generated because of drilling processing, therefore must be removed the operation of the burr, and this operation is because must be driven off pore depth
The burr at place and be not easy, and it is time consuming.In addition, since machining is more, cause blank resection big, material benefit
It is low with rate.Since factors above causes manufacturing cost to increase.
Japanese Unexamined Patent Publication 2000-343136 bulletin proposes a kind of manufacturing device of thick-wall bend, using as solving above-mentioned class
The countermeasure of topic.But be bent start when and at the end of variation of the both ends of the surface at a distance from the centre of gyration of heavy wall pipe 5 subtract
It is small, the small thick-wall elbow blank of dimensional discrepancy can be made.As a result, the blank that bend pipe is made in thick-walled pipe can be cut, is not necessarily to
Prepare rough forging, and because using thick-walled pipe to bore processing without be used to form the pore of fluid channel.In addition, also not
Carry out over the burr removing steps of the drilling crossover sites continued to use always.Furthermore reduce because using round thick-walled pipe
The surplus of screw thread process.In this way, it is not necessary to target drill, it is not necessary to drilling and deburring operation, the cutting output of screw thread process
Less, therefore when processing can be greatly reduced it asks, reduces tool cost, and stock utilization can be improved.However this device
Upper rail have a circular arc shaped guiding face, when making upper rail must first processing block reprocess circular arc shaped guiding face 21la, cause plus
Work amount is big, and processing is also complicated, as a result increases processing cost.
In order to complete technical problem present in Japanese Unexamined Patent Publication 2000-343136 bulletin, the Chinese invention occurred as soon as is special
The manufacturing device and manufacturing method of thick-wall bend disclosed in sharp CN1212903U, the manufacturing device and Japanese Unexamined Patent Publication 2000-
Manufacturing device in No. 343136 bulletins, which is compared, has structure simple, and manufacturing cost is low, long service life, can also utilize heavy wall
Tubing manufacture dimensional accuracy it is high match effective elbow blank.
Exist in manufacturing device in order to be further improved thick-wall bend disclosed in Chinese invention patent CN1212903U
